Read a lot. Then when you’re tired, read some more. Read things you agree with and read things you don’t. Sit with that discomfort - discomfort leads to growth.
Read books on our justice system - its successes and failures. Read Anita Gets Bail by Arun Shourie and also read The Colonial Constitution by Arghya Sengupta. Read To Kill a Mockingbird. Read Zia Mody’s book and read Madhav Khosla and Gautam Bhatia.
If you must, watch some movies. Watch Twelve Angry Men and watch Gangajal. That cuts a fairly vast swathe across what you can expect to find in the profession.
If I can be slightly selfish, please also read the financial papers - Mint is a good one. Read The Morning Context. Subscribe to Money Stuff. Maybe read Barbarians at the Gate and The Smartest Guys in the Room?
If you don’t like reading, why are you in law school?
